{"version":"1.0","type":"rich","title":"New York Census Tracts","description":"This example displays New York Census Tracts as gray polygons with black borders, rendered as SVG paths that fill the viewport. Loading GeoJSON via `d3.json` and converting TopoJSON with `feature`, the map uses `d3.geoPath` without a projection. The visualization supports interactive panning and zooming through `d3.zoom`, which applies transformations to a group element. Hovering changes a tract’s fill to red via CSS. Data comes from Mike Bostock’s New York Census Tracts block, using TopoJSON and D3 v5.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b5ef9d78a35445eb90b5fec615f65652?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
